MACHINE FOR DISINTEGRATING CLAY, CLAY-SHALE, 85C.

SPECIFICATION forming part of Letters Patent No. 351,617, dated October26, 1896.

Application filed August 6, 1886.

T0 alt whom, it may concern:

Be it known that I, JAMES C. ANDERSON, a

land Park, in the county of Lake, State of Illinois, have inventedcertain new and useful Improvements in Machines for Disintegrating Clay,Clay-Shale, &c., of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to improvements in machines for reducing clay,clay-shale, and other material.

The object of my invention is to provide clay-shale, and other materialin which thetwo cones revolve in opposite directions, so that there willbe formed two currents of the material, the collision or impact of whichreduces the particles without serious wear and My invention consistsoftwo independentlyrevoluble cones, (one working within the other,)theinside of the larger cone being pro vided with a series of cells, whilethe outside of the smaller cone is provided with similar cells, theobject of which is to hold the material which lies next the cones sothat it will not slip or wear the faces of the cones while the materialto be reduced is carried in opposite directions by centrifugal force,and the reduction is effected by the impingement or contact of the twooppositely-moving currents of the material.

My invention consists, further, in certain details of construction,which will be more fully described hereinafter, and pointed out in theclaims.

Referring to the drawings, Figure 1 is a top or plan view of my improvedmachine. Fig. 2 is a vertical longitudinal sectional view of the same.Fig. 3 is a vertical sectional view on the line as x of Fig. 2. Fig. 4is also a sectional view on the line x of Fig. 2. Fig. 5 is a side Viewof the smaller cone, showing the cells in the periphery thereof. Fig. 6is a detached portion'of the cone shown in Fig. 5, with the cellsformedtherein. Fig. 7 is asectionztl view of the sameon the line 7, y ofFig. 6.

Gris a hollow cone or frustum of a cone having the hollow trunnion H.which is mounted in suitable bearings in the standard B, said trunnionbeing provided with the band-wheel I, by which it is rotated in adirection the reverse of thecone D, heretofore described. The interiorof the cone G is provided with cells I), which are of the same oressentially the same, construction as those described in regard to thecone D. The hollow trunnion, which forms the bearing or support for thecone G passes through the end wall of said cone, and forms an openingthrough which the material to be reduced is fed into the cavity betweenthe two cones.

K is a feed-hopper mounted on the brackets or supports B, which has aprojection, L,

that extends through the hollow trunnion H, and in which is located ormounted the feedscrew M, said screw being driven by the bandpulley N.

It will be noticed that the trunnion H surrounds the projection or tubeL, and that the action of the feed screw or conveyer M tends to wear theextensionL, instead of acting directly on the interior of the hollowtrunnion,

as has heretofore been practiced, thus pre venting the trunnion frombeing rapidly worn away or destroyed.

As before indicated, the material to be reduced is fed centrally intothe space between the two cones, and the walls of the cones aregradually contracted at their outer or larger ends, so as to narrow thechannel through which the material is driven by the centrifugal actionof the rapidly-revolving cones, by which means the flow of the materialis re tarded, and a more thorough reduction of the material is insured.

By forming a series of cells on the two redm-ing-snrfhces of the conesthe material is held or clutched by said cells, and twooppositely-traveling currents of the material are set up, whichimpinging the one against the other, a rapid and effectualdisintegration of the material takes place without wearing or injuringthe surface of the cones to any great extent.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. In a machine for reducing clay, clayshale, and other material, thecones D G, having cells in their outer and inner surfaces, re-

spectively, said cones being adapted to be driven in opposite directionsand to receive the material through a central feed-opening, asdescribed.

2. In a machine for reducing clay, clayshale, and other material, thefeed-hopper K, provided with the extension or tube L, in which theeonveyer or feed-screw is located, in combination with the trunnion Hand cones D G, whereby the rapid destruction of the trunnion isobviated, as set forth.

In testimony whereof I my signaturein presence of two witnesses.
